The search engine first filters search terms in several ways. An M followed by a space or hyphen has the space or hyphen removed, so that searching for Messier catalogue objects is simplified and a user input of M45, M 45 or M-45 all result in the same query being executed; similarly, NGC designations and common search terms such as Shoemaker ...
An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years, NASA says — with the space agency saying it "no longer poses a significant ...

Near-infrared spectral data obtained by NASA's Infrared Telescope Facility in 2018 suggests that 2001 FO 32 is a stony asteroid classified under the Sr spectral class. [ 5 ] 2001 FO 32 was first observed with radar on 21 March 2021 at Canberra, Australia and Narrabri, New South Wales , which provided refinement of its orbit.
On 3 September 2003 a NASA press release wrote, . Newly discovered asteroid 2003 QQ 47 has received considerable media attention over the last few days because it had a small chance of colliding with the Earth in the year 2014 and was rated a "1" on the Torino Impact Hazard Scale, which goes from 0 to 10.
The asteroid with the greatest chance of impacting Earth in 2025 is 2009 VA (6-meters in diameter) with less than a 1-day observation arc. [8] It has a 1:48,000 chance of impact on 06 November 2023, but is expected to be around 0.3 AU (45 million km ) from Earth on that date with uncertainty region of ± 900 million km. [ 10 ]
It was discovered by ATLAS South Africa, Sutherland on 16 June 2024. [2] This asteroid travels in both the main-belt and in the near-Earth region. It passed Earth on 29 June 2024 at a distance of 184,000 miles (295,000 kilometers). That distance is about 0.77 lunar distances (LD). [2]
1994 CC was discovered by Spacewatch's Jim Scotti at Kitt Peak National Observatory on 3 February 1994. [2] In June 2009 it was shown to be a triple system, i.e. the largest body is orbited by two satellites; only about one percent (1%) of near-Earth asteroids observed by a radar are found to be triple systems such as this one.
